Hi. Are you porting to x86 or Alpha? I've been so happy with eg77 (Debian's g77) on PPro and PII machines that I was able to avoid trying those other choices (Portland, Absoft, etc.). The optimization up to level 3 (-O3) has worked just fine on the Intel platform in my experience, and most f77 programs port without any changes. Of course, Digital's f77 with the -O4 switch produces faster code per MHz on our 600MHz alpha runing DUNIX. Anyway, sorry I can't be of any help, but I'll be following this thread to see if anything interesting comes up. Thanks.
